wtf are you talking about? Until late last year for the past 6 years before that, they had exactly one adapter profile - magsafe. Recently they added a 2nd profile, and introduced an converter so old bricks can still be reused (which I'm doing right now). You can even use an underpowered brick - don't expect your high-wattage MBP to charge as fast, but it works.

Apple is one of the good guys here. Compare/contrast with Sony or Dell - it's night & day.
